a This invention relates to an interleaved paper container and dispenser and particu-, larly to alocking mechanism therefor.

The objectof the. present invention is to generally improve and simplify the construction and operation o-f devices of'the character described; to provide a container and dispenser for interleaved; paper, such as paper towels, toilet paper, etc. and to particularly provide a simple readily applied. key actuated locking mechanism for locking thecontainer so that it cannot be opened except by the attendant or one in possession of the proper key. 7 Y 7 The invention is shown by way of illustration in the accompanying drawings inrwhich:

Fig. 1 is a central vertical longitudinal secon through t e c nt iner an -th locking mechanism,

Fig. 2 is a perspective view of the upper end of the back plate, a

Fig. 3 is a perspective tated plate,

Fig. 4 is a perspective view of the key, Fig-. 5 is a perspective view of the latching mechanism of the lock, 1

Fig. 6 is a plan view of the same. Referring to the drawings in detail and particularly Fig. 1, A indicates a rectangu- 30 lar-shapedback plate .which is adapted to be secured to a wall or any other suitable sup port by means of screws or the likeindicated at 2 and pivot-ally attached to the lower end of the back plate as at 3 is a housing consist- View of the key robottom plates as indicated at 6 and 7 respectively. The housing forms a receptacle for interleaved sheets of paper such as indicated at 8 and they are removed one by one through an opening 9 and the bottom section 7 in the usualmanner. The pivotal mounting of the housing permitsit to be swung outwardly from the wall and the back plate A in the direction of arrow a (see Fig. 1) when it is desired to insert a new supply of paper, but means are provided for preventing unauthorized opening of the housing, the means employed being a locking mechanism generally indicated at B. This locking mechanism is best illustrated in Figs. 2 to 6 inclusive. The

- ing of a front plate a, side platesfi and topand lockproper consists of a plate ,10 is bent upon itself as indicated at 11-1 Thisplate is cut away as indicatedat 12 to. permit apair of lugs 13 to extend upwardly through the same and the forward end of the plate ter Inmates in a pair of-hook-shaped latching members 14. The ends of the plate 10 arejextended to formapair. of supporting lugs 15 and the-forward edgeof theplate 10 is extended to form a second pair of supporting lugs, as indicated at 15 The plate as awhole is preferably, made of" thin, cold-rolled sheet steel or thelike asacertain amountiof springlness, is,required, as far as the upper portion of the plate isconcerned, i. e., suflicient fiex-- ibility is required to insure raising. and lowering of the latch members 14L. Mounted on the plate l0 as shown in Figs. 1, 5 and 6 is a substantially circular plate 16. This plate is provided with two small semi-spherical shaped projections 17' and 18, and its center portion is-cut-away to permit the formation of the lugs 13. The plate 16 is secured to the lower plate 10 by. a rivetor the like as indicated at 19 audit is free. to rotateabout the same. On the upper portion of the latching mechanism shown in Fig.- 5is across bar 20 on which is formed two cam surfaces 17*: and 18. These cam, surfaces are engaged by the projections 17 and 18on the plate 16-when thls is; rotated, and the latches 14 are thus raised. I

Formed on the upperend of the back plate (see Figs. 1 and '2) is a forvvardly projecting flange 22 and formed in said flange is a pair ofropenings 23 through which'the latches 14 are adapted to project. A cross bar 24 is formed at the lower edge of each opening 23' and the latches interlock therewith when the lock assumes a'lockedposition, as shown in Fig. 1.' The flange 22 isalsocut away,;as indicated at 25, this cut away portion being sufficiently large to allow ample space for the front supporting lugs 16 (see Fig, 5) of the plate 10., a j

In actual operation, it will be seen that a key is required to open the lock. 1 This key is shown in Fig, 1. It consists of a head portion 26, a shank 27, a pair of side wings 28, andia' oint-i29- .This,k y' s nserte t mue a slot 30 which is formed in the upper part of the housing. When it is fully inserted, the point of the key enters the tubular rivet 19, while the wings 28 of the key will lie between the lugs 13. Hence, when the key is rotated the wings of the key engage the lug 13 and the plate 16 will also rotate. During such rotation the projection 17 engages the cam member 17 a on the cross bar 20, the projection 18 and the cam member 18*. The whole upper ,plate,to-wit, the latches 14 and the crossbar 20 will thus be swung upwardly aboutthe folded rear edge 11 and the latches will thus be raised out of engagement with the cross bars 24. When this position is assumed, the lock is unlocked andthe housing may be swung about the pivotal support 3 in the'direction of arrow (1, thus opening it sufiiciently to insert a new supply of paper. The key may be removed the moment the housing is opened and when it is refilled with paper and it is desired to close the same, it is only necessary to swing the housing towards the back plate A, as the latches will then ride over the cross bars and will snap downwardly, behind the same due to the inclined faces 31 presented.

The whole locking mechanism in reality is exceedingly simple as the number of parts employed are only 3, i. e., the latching unit consists of a single plate 10 which is bent along the edge 11 to form the cross bar 20 and the latches 14. This forms one member of the lock. The second member is the rotating plate 16, and the third member is the flange 22 formed on the back plate which carries the cross bars 24. The key is also simple as it merely consists of a head, a shank and a pair of wings. Neither the key nor the mechanism is thus liable to get out of order, and furthermore, the simplicity of the structure permits rigid parts to be employed.

The latching unit shown 1n Fig. 5 may be attached to the top plate 6 of the housing in any suitable manner, but as supporting lugs 15 and 16 are provided it is only necessary to punch them to secure the latching unit by means of rivets or the like.

' ,Vhile the lock mechanism has been described in conjunction with a container and dispenser for interleaved papers and the like, I wish it understood that its use should not be limited thereto, as it maybe applied to numerous types of containers, boxes, covers, etc. And further, I wish it understood that various changes may be resorted to within the scope of the appended claims. Similarly, that the materials and finishes of the several parts employed may be such as the manufacturer may decide or varying conditions or uses may demand.

Having thus descrlbedm'y invention, what I claim' and desire to secure by Letters Pat ent is v V l. The combination with a container having a hinged cover section and a stationary section of a locking mechanism therefor, comprising a plate secured to the cover section and spaced therefrom, a resilientlatch formed integral with the plate and lying between the plate and the cover, latch retaining means on the stationary section, and key actuated means whereby movement is imparted to release the latch with relation to the retaining means.v

2. The combination with a container having a hinged cover sect-ion and a stationary section of a locking mechanism therefor, comprising a plate secured to the cover section and spaced therefrom, a resilient latch member formed integral with the plate and lying substantially parallel with said plate, in the space between the plate and the cover, latch retaining means on the stationary section, and key actuated means interposed between the latch and the plate whereby movement is imparted to release the latch with relation to the retaining means.

3. The combination with a containerhaving a hinged cover section and a stationary section of a-locking mechanism therefor, com prising a plate secured to'the cover section, a

latch member lying substantially parallel with said plate, a resilient connection between one end of the latch and the plate, a

centrally pivoted plate interposed between the first-named plate and the latch member, a pair of lugs on said plate adapted to be en gaged by a key to impart a rotary movement to the plate, and a projection on said plate engageable with the latch to release it with relation to the latch retaining member.

4. In a device of the character described, a plate bent back upon itself to form a resilient section, a pair of latch members on the free end of the resilient section, a second plate pivotallysecured to the first-named'plate and interposed between said plate and the resilient section of the plate, a pair of lugs on the rotary plate adapted to be engaged by a key to impart a rotary movement to the rotary plate, 7 a cross bar connecting the latches and movable in unison with the latches, a pair of cam members on said cross bar, and 'apair of projections on the rotary plate engageable with the cam members to raise and lower the.

latches with relation to the first-named plate. 5. In 'a lock of the character described, a rigid platehaving a section thereof bent back upon itself to form a resilient plate, a pair of lugs formed on the rigid plate, one on each end thereof, a housing to which said lugs are secured, a latch member formed on the free end of said resilient plate, and a key actuated mechanism for moving the latch member to and away from the rigid late.
